Biological sulphate reduction in wastewater treatment

The sludge line accounts for about one-quarter of total wastewater treatment costs. Minimising the volume of excess sludge would therefore lead to considerable cost savings. Sulphate-reducing bacteria (SRB)…

Removing H2S from biogas using granular iron(hydr)oxide

Aquafer is a sludge consisting of ferric oxide/ferric hydroxide, which is a residual of drinking water treatment processes. Reststoffenunie (now AquaMinerals) looks after the disposals of the aquafer…
